The common sand flea (agile orchestra or O. Plateau shrimp (jumping hook shrimp) from Greenland to Argentina's European coast and East Atlantic coast is about 1 cm (0.4 inch) long, dark brown or gray, light blue tail and reddish brown tentacles, and lives on wet beaches.

Generally speaking, sand fleas hide in the sand during the day and come out from their hiding places to look for food at night. And those Africans who are barefoot because of poverty, once they pass by, are likely to become the prey of these sand fleas.

Living habits

Insects of this order usually look for the host in the cave where the host lives, but in the environment where the host is abandoned, birds move out and slip away, and they rely on touch (warmth, airflow, etc. ), odor (carbon dioxide, body odor, etc. ) or visual (scanning) approach and find the owner in a short distance. Some jumping fleas can jump about 200 times their body length. Other flea species living in high nests or special environments are safer than jumping, and there are even some flea species that can't jump at all.

This insect often migrates and changes hosts. Host migration, dispersion, seasonal migration, tunnel crossing, infection and death, cannibalism, hunting of beasts and humans, and migration, dismemberment and dispersion of fleas themselves provide opportunities for fleas to migrate and change their hosts (individuals or species). In particular, epidemic diseases lead to host death and flea corpse separation, which has epidemiological significance between humans and animals and deserves attention.
